Slide to open or close the screw cover 
to reveal the battery compartment 
case and 

PAIRING

 button.

2 –  Back cover

Slide to open the screw cover and unscrew 

the screw until the battery compartment 

case is separable from the back cover.
Separate the battery compartment case 

from the back cover.

Install Motion Sensor Battery

NOTES

Use only CR123A Lithium Battery.
When inserting battery, ensure polarities are 

correct.
For proper operation, use battery within the following 
temperature range: 0°F (-18°C) and 130°F (49°C).

Pull the ribbon tightly across the battery 

compartment.
Insert the battery into the battery 

compartment.

Add and register a sensor

You need to register your new 

VC7003A

 Contact 

Sensor to your 

VC7151-102A/VC7151-202A/

VC7151-302A 

telephone system.

Register a Motion Sensor:

If you have just inserted the battery, wait 

for the red LED to stop flashing.
Press and hold 

/HANDSET LOCATOR

 on 

the telephone base for about 4 seconds until 

the 

IN USE

 light turns on. The telephone 

base shows 

Registering... Please wait

Use a narrow pointed object such as a 

pen to press and hold the 

PAIRING

 button 

on the Motion Sensor, until the LED light 

at the front side flashes green. The sensor 

is now registering to the telephone base.

The registration process takes about 90 

seconds to complete. When this registration 

process completes, the green LED light 

on the sensor will remain steadily on for 

approximately two seconds then, will turn off.
If registration fails, remove battery from the sensor 

and wait for a few seconds. Then, re-install 

battery and wait until the red LED stops flashing. 

After that, begin registration process again.

NOTES

If you are going to mount the sensor with screws or 

mounting bracket, the back cover has to be mounted 

before you assemble the battery compartment case 

back to it (see 

Mount the sensor

).

Replacing a sensor

If you have purchased this new 

VC7003A

 

accessory sensor to replace an old sensor, follow 

the instructions to deregister your old sensor. 

VC7151-102A/VC7151-202A/VC7151-302A

 

telephone system can support up to 30 sensors.
To replace a sensor, deregister the registered 

sensor first, and then register this new sensor 

to the telephone base.

To deregister a sensor on VC7151-102A/

VC7151-202A/VC7151-302A telephone system:

1.  Press 

MENU

 when the phone is not in use.

2.  Enter the code 

*33734#

 to access the 

DEREGISTER

 menu.

3.  Press   or   on the handset, or 

CALLS

 /   

or 

PHONEBOOK

 /  to scroll to 

Single 

sensor

, and then press 

SELECT

.

4.  Press   or   on the handset, or 

CALLS

 /   

or 

PHONEBOOK

 /  to scroll to the sensor 

to be deregistered, and then press 

SELECT

.

5.  Press 

YES

 to confirm the deregistration.

The telephone base shows

 Motion X is 

deregistered

 and you hear a beep when the 

deregistration process completes.

Motion detection

The Motion Sensor detects motion with 

one-minute cool off time. Once motion is 

detected, the sensor will start detecting 

motions again only after one minute.
The Motion Sensor is more sensitive in 

detecting motions crossing the space in front 

of the sensor than that moving towards the 

sensor.
The Motion Sensor can detect motion 

occurring at distances up to 

40 feet  

(12 meters)

 when it is mounted at a height  

of 

7.9 feet (2.4 meters)

.

It is recommended to mount the sensor at the 

height between

 6.2 feet (1.9 meters)

 and

 7.5 feet 

(2.3 meters)

 for optimal detection coverage.

For motion detection of babies or pets:

If you use the Motion Sensor only to detect 

the motion of babies or pets, you can mount 

the sensor at a lower position to shorten 

the minimum distance before reaching the 

detection area. It is recommended to mount 

it at the height 

3.3 feet (1 meters)

 for optimal 

detection of babies and pets.

NOTE

The numerical values in the illustrations are for 

conceptual reference only. The actual angles 

and distances may vary upon the change in the 

mounted height of the sensor.

Check the sensor before use

1.  Place the sensor about 

3.3 feet (1 meter) 

from the telephone base.

2.  Waive your hand or walk across the area 

in front of the sensor.

You will receive alerts at your telephone 

base. Refer to the Installation guide or 

user’s manual of your telephone base 
for the sensor alerts.
The LED light on the Motion Sensor will 

flash red once.

NOTE

Once motion is detected, the sensor will only 
start to detect motion again after one minute. 
When you have received alerts already, you will 
only receive alerts again for motion detected 
after one minute.

Test the sensor signal strength

You can mount the Motion Sensor at a 

location where family members or unwanted 

visitors are likely to be coming and going.
1.  Take the sensor to the desired mounting 

location and then, hold it at the desired 

height (Refer to 

Motion detection 

section). Use adhesive tape to hold the 

sensor temporarily in place.

2.  Enter the 

Check signal

 mode under the 

Sensor setup

 menu at your handset to 

test the sensor signal strength.

3.  Waive your hand or walk across the area 

in front of the sensor again and check 

whether a good signal is received at your 

telephone base.

NOTES

Once motion is detected, the sensor will only 
start to detect motion again after one minute. 
When you have received alerts already, you will 
only receive alerts again for motion detected 
after one minute.
If there is no alert received when you walk 
across the area in front of the sensor, move 
your telephone base closer to the mounting 
location or move the sensor closer to the 
respective product.
Depending on surroundings and obstructing 

factors, like walls or cabinets, the sensor may 

not transmit to the telephone base properly.

Mount the sensor

NOTES

This sensor must be mounted vertically on wall. Do not mount the Motion Sensor in a horizontal 
orientation, or flat on the ceiling. 
Make sure the mounting surface is clean. A textured surface or any imperfections to a smooth surface 
can keep the mounting tape from making a strong bond.
This device detects or performs better when provided with a constant and stable environment.  
Avoid placing the sensor at a location which faces direct sunlight, or exposes to areas that may change 
temperature rapidly, or where there are air ducts or substantial airflows.
The recommended mounting height for motion detection of adults is between 

6.2 feet (1.9 meters)

 and

 

7.5 feet (2.3 meters)

, and that for babies or pets is about 

3.3 feet (1 meter)

.

If you drill the holes into an object other than a stud, insert the screw anchors into the holes and tap 
gently on the ends with a hammer until the screw anchors are flush with the wall or ceiling.

TIP

You can choose to mount the sensor with the mounting tape first. Remove the mounting tape and use 
screws later if you decide to mount it at that location for long term.
